e*thirteen Quick Fill Schrader Tubeless Valves bring together the best of both valve worlds: combining the legendary durability and high airflow of Schrader valves with the innovative Quick Fill injection system that makes tubeless setup effortless. Featuring the same game-changing 4-part design as our Presta valves, sealant injects directly from the bottle nozzle into the tire without passing through the valve core, breaking the tire bead, or needing any tools. No stress, no mess. Schrader valves deliver superior airflow compared to Presta, are less likely to clog, and their larger diameter makes them more resistant to impact damage. Say goodbye to tiny valve core pins that bend and constant checking if nuts are tight and sealing. The robust Schrader design provides long-lasting durability you can trust. The valve cap end is perfectly sized to depress and release air when needed. Best of all, these valves work with standard air compressors without expensive adapters, making inflation at gas stations or with shop compressors simple and convenient. Sharing the same CNC-machined alloy and rubber base as our Presta version ensures compatibility with standard Presta-drilled rims and tricky tire inserts like CushCore. Available in two length options to fit almost any rim on the market: short stem (12.5-24mm depth) fits Grappler, Sylvan, Optimus, LG1, TRS, and alloy XCX rims; long stem (23-31mm depth) fits Piedmont and XCXr rims. Choose from the full Helix color range (Black, Bronze, Naranja, Eggplant, Intergalactic, and Sterling Silver) for beautiful builds that coordinate with e*thirteen stems, cassettes, cranks, and chainrings. Sold as a pair.
